Cygnus Ultrasonic Thickness Gauges
Cygnus Ultrasonic Thickness Gauges all measure using the Multiple-Echo Technique for accurate error-checked metal thickness.
Request This ServiceThis uses multiple pulses, providing verified thickness readings and allowing coatings up to 0.787 inches thick to be ignored. Our UT thickness tester range now includes several PLUS+ models which also feature Single-Echo and Echo modes for measuring extreme corrosion and pitting
Our measuring modes page provides guidelines on the use of each measuring mode. The Surface range of thickness gauges includes Intrinsically Safe for potentially explosive environments; Hands-Free; large LCD display, linear data logging, simple menu operation; and the PRO with comprehensive data logging, A-Scan, and B-Scan for professional users. The Subsea range of thickness gauges consists of the wrist-mounted DIVE and the handheld Underwater thickness gauges; ROV mountable series for use on small, medium to large ROVs with optional probe handling solutions. Manufactured in the UK, and are built to last (3-year warranty).
